Catalytic reaction solid phase density
Thread Content
What are the reasons for the increase in the solid phase density of the catalytic reaction and the density at the inlet of the centrifuge, as well as why does the temperature of the waste agent remain at 150 degrees without dropping?
The increase in the density in the regenerator’s dilute phase and at the inlet of the cyclone may indicate the occurrence of carbon packing. I don’t know what waste agents are If the temperature of the balance agent received by the balance agent tank continues to not drop, it further proves that carbon accumulation has occurred. The balance agent tank is normally filled with industrial air, which reacts with the catalyst containing coke and releases heat. In other words, the coke that should have been burned in the regenerator is transferred to the balance agent tank where it continues to burn, resulting in the temperature of the balance agent tank either not dropping, remaining constant, or decreasing only slowly. Be careful not to burn out the balance agent tank.
It’s a three-spin waste reagent storage tank~! The phase density was around 0.5 kg/m3 initially, rose to 16 kg/m3 within 1 month, then dropped back to around 6 kg/m3. Moreover, the temperature inside the waste reagent tank remained high, with no significant leakage of the reagent
I fully agree with the view expressed in post 2. If carbon accumulation occurs, it will also be reflected in changes in the regenerator temperature. Pay attention to the amount of steam rising in the raw material lift pipes, as well as the oil yield over the past few days – these values will change. Additionally, as the density of the dilute phase increases, does the main air flow rate change? Could the catalyst be undergoing hydrothermal deactivation, which leads to an increase in fine catalyst particles inside the regenerator?

The main air distribution is poor, resulting in bias flow in the dense-phase bed. 3. If carbon accumulates, the oxygen content in the regenerator will gradually drop to zero; the regeneration temperature is low, the reaction depth is low, and the temperature difference between the dense and dilute phases is zero. In severe cases, the centrifugal pressure drop increases, the catalyst particles become larger, and their color darkens, which can be observed and used as a basis for judgment through sampling.
Carbon buildup won’t occur; the oxygen content in the flue gas is between 5 and 8. It might be that there is too much fine powder of the catalyst itself
Weren’t you saying the performance enhancer isn’t that strong? Judged from the persistently high temperature of the three-spin waste tank?
